Fasting Q&A with Dr Jason Fung: Broccolini, Metformin, Exercise and Weight Loss, and More

Episode #149

In this Fasting Q&A episode, hosted by Coach Lisa Chance, Dr. Jason Fung answers questions from the TFM Community:

1. I've heard you've written an amazing book called, "The Cancer Code." I haven't read it yet, but wanted to hear your thoughts on broccolini being an anti-cancer food. I understand it contains Sulforaphane, Indole-3-carbinol (I3C), Glucosinolates, Vitamin C, and fiber. Should I concentrate on cruciferous vegetables, like broccolini, or just work on getting a balanced diet? What are your thoughts? [02:14]
2. I have a little confusion about the difference between taking metformin and injecting insulin. From what I've read in your books it's that insulin is going to make type 2 diabetes worse in the long run. I already know that that's not the answer to reverse type two diabetes and I'm not taking either one. Like insulin, will metformin also be detrimental to treat T2D or is there a difference between one and the other - and why, please? [05:27]
3. What do they mean by 'immunoreactive insulin'? [12:06]
4. Does the liver respond negatively to the ingestion of supplements? In other words, do the supplements cause any changes in my insulin? [14:52]
5. I started TRE (beginning Jan this year) at about 135 pounds and am now doing 24-hour fasts with OMAD and 2MAD. I have completed a 42-hour fast and will probably try another one this week. I am eating whole foods. Avocados are my miracle!!! I do not snack between meals. My body is still releasing weight with what I am doing now and I feel I have another 5 pounds to go. How will I know when to stop shedding the weight? [18:13]
6. Can you clarify the role of physical activity and exercise in weight loss? In The Obesity Code, you shared that a number of rigorous clinical trials demonstrate that exercise contributes minimally, if at all, to weight loss. However, zone 2 exercise is promoted for its'fat burnin' benefits. I plan to continue exercising for its health-promoting benefits but I would really like to hear your take on the extent to which it can assist with weight loss, and what exercise types you recommend for weight loss. [21:56]
7. On non-fasting days, what is Dr. Fung's chosen style of eating? [29:46]
